It blew my mind how much faster my GTX 1070 was able to complete a 10,000,000 word dictionary attack on a hash in 52 seconds, when the same operation on a 3.0 Ghz Core i5 took 8 hours and 14 minutes. That was easy, no? Cracking ConsiderationsĪt the end of the last article I talked a little about the importance of using GPUs while attempting to brute force hashes. This command will produce a file called, in this instance, capturefile-01.hccapx. cap2hccapx capture-01.cap capturefile-01.hccapx I’ll be using the filename from the previous example in my syntax here, so obviously you’ll want to change the syntax if your capture filename is different. hccapx is a quick and dirty single-command affair. To check and make sure that it’s working properly, you can attempt to execute it from the command line while in any working directory by running “cap2hccapx.” You should get the following output.Ĭonverting the. You’ll only have to do this once, and once the cap2hccapx binary is in your /bin directory, you’ll be able to use it indefinitely. Plus, compiling your own binary and being able to do it all locally from the command line is so much more satisfying anyway. Optionally, you can go online and use the online tool provided at to convert cap files to hccapx files, but for some reason I couldn’t get this to work.

You can also get rid of the source, since we won’t need it anymore. Doing that is simple enough with one command. That way you can use the command no matter where you are in the Linx filesystem, since /bin is already in the system path. The easiest way I’ve found to use this is to move that file to the /bin directory. An executable file called cap2hccapx will be created. Whichever way you’re able to grab it, you can compile the file with the following command.

I’ll host a copy of the file for archive purposes in case the above file disappears. cd ~Īt the time of this writing, that’s where the file is located. The simplest way is to open a shell on Kali, change directories to your home directory (if you aren’t there already), and get the file via the wget command. The first thing you’ll want to do is get a copy of the cap2hccapx.c source code.

hccapx, you can use Hashcat on your Kali machine to crack the file, or if you have a Windows gaming rig with a GPU or two in it, fear not… Hashcat is available for Windows as well and you can just as easily crack it there. Compiling it in Kali Linux is a single command, and Kali already has a C compiler installed by default (gcc). They have released an open source utility for this, but it’s not downloadable in a pre-compiled form. Hashcat prefers those files be converted over to its own format, which ends in.

Somewhat recently, Hashcat was updated and now doesn’t get along with. Downloading and Compiling the cap2hccapx Utility If you missed either of those articles, please go check them out.

In the previous two articles in this series I covered how to set up an external USB Wi-Fi adapter and put it in to monitor mode, and talked about how to capture a WPA2-PSK handshake for the purposes of taking it offline to crack.
